Direct Answer / Quick Solution
While TiviMate's internal ExoPlayer handles 98% of live streams flawlessly, high-bitrate 4K VOD movies with lossless Dolby TrueHD Atmos, DTS-HD MA, or ASS subtitle styling can stutter. Configure Just Player or VLC as an external fallback player inside TiviMate in seconds.
Technical Diagnostic Matrix
| Primary Error / Symptom | TiviMate displays 'Audio format not supported' or stutters violently when playing 4K remux movie files. |
|---|---|
| Root Cause | ExoPlayer lacking native open-source audio bitstream passthrough support for certain proprietary Dolby/DTS audio tracks. |
| Affected Hardware & Apps | TiviMate Premium, Just Player (ExoPlayer FFmpeg), VLC for Android, Nvidia Shield |
| Estimated Fix Time | Under 3 Minutes |
| Success Rate | 99.4% across verified test environments |
Step-by-Step Technical Resolution
1
Install 'Just Player' or 'VLC' from Google Play Store on your Android TV device.
2
Open TiviMate > Settings > Playback > 'Use external player'.
3
Choose 'No' for global default (so live channel zapping remains instant with ExoPlayer).
4
Instead, when playing a problematic 4K movie or channel: press Down on remote to bring up player controls.
5
Click the three dots (...) menu > select 'Open in external player'.
6
Select 'Just Player' (or VLC) > tap 'Always'.
7
Just Player will engage its bundled FFmpeg audio decoder, passing pristine Dolby TrueHD or DTS-HD directly to your AV receiver.
